Question 2: Reading a line plot (2 points)
Use the line plot of ribbon lengths.
- Count the ribbons that are \(1\text{ ft}\) long. (1 point)
- Name the length that appears most often. (1 point)
Question 3: Counting and comparing (2 points)
Use the line plot of screw lengths.
- Count the screws that were measured. (1 point)
- Count the screws that are longer than \(1\frac{1}{4}\text{ in.}\). (1 point)
Question 4: Make a line plot (3 points)
Use the widths of 8 buttons that Priya measured, in inches: \(\frac{1}{2}\), \(\frac{3}{4}\), \(\frac{3}{4}\), \(1\), \(1\), \(1\), \(1\frac{1}{4}\), \(1\frac{1}{2}\).
- Copy the number line and make a line plot of the data. (2 points)
- Count the buttons that are wider than \(\frac{1}{2}\text{ in.}\). (1 point)
Question 5: Subtracting from a plot (2 points)
Use the line plot of tomato plant heights.
- Find how much taller the tallest plant is than the shortest plant. (1 point)
- Find how much taller the tallest plant is than the most common height. (1 point)
Grade 4 Line Plots Test: questions 6–9
Question 6: Adding from a plot (2 points)
Use the line plot of the clay snakes Liam rolled.
- Find the total length of the longest and the shortest snake. (1 point)
- Find the total length of the two snakes that are \(1\frac{1}{2}\text{ in.}\) long and one snake that is 1 inch long. (1 point)
Question 7: Total length (3 points)
Find the total length of all the wood scraps Ethan has, shown on the line plot. Write the answer as a mixed number.
Question 8: Find the mistake (2 points)
Explain Maya’s mistake (1 point) and find the correct difference (1 point). Maya subtracted \(5\frac{1}{4} – 2\frac{3}{4}\) and wrote \(3\frac{2}{4}\).
Question 9: Multi-step problem (2 points)
Find how much longer the longer ribbon is than the other ribbon after the cut. Sofia measures two ribbons: one is \(3\frac{1}{4}\text{ in.}\) long and the other is \(2\frac{1}{4}\text{ in.}\) long. She cuts \(\frac{3}{4}\text{ in.}\) from the longer ribbon.
